Node API to merge PDF to PNG

Node Cloud SDK to combine PDF files and export the result to PNG format

Use Node library to merge PDF to PNG via REST API. Easily combine two or more PDF files into a single PNG file using Node.

Combine PDF to PNG using Node REST API

Easily merge PDF documents and export the result to PNG graphic format in Node code. This Node library is designed to combine multiple PDF files into a single PNG image using the REST API, i.e. by passing HTTPS calls over the Internet.

This is a professional Cloud-native PDF to PNG merging solution that provides Node programmers with both great development flexibility and powerful features. By merging documents, you can automate your digital PDF/PNG workflows and offload some routine parts of the process to fast and efficient PDF processing Node software.

Merge several PDF into one PNG image in Node

You may need to combine PDF files into a single PNG image in many cases. For example, you may want to combine multiple PDF files together before printing or archiving.

PDF merging can be part of a whole integrated document-processing approach for generating PNG images from disparate data sources. Such tasks involve the use of a full-featured PDF/PNG manipulation Node library that will process a set of PDF files and merge them together in the shortest possible time, producing a compact and accurate graphical output.

Merge PDF to PNG in Node

To perform PDF to PNG merging in Node, you need at least two source PDF documents. For a quick start, please check out the Node code example below.

Upload files you want to combine
Output format
Select the target format from the list
import * as fs from "fs";

const wordsApi = new WordsApi("####-####-####-####-####", "##################");

const document = fs.createReadStream("Input1.pdf");
const mergeProps = new model.DocumentEntry({
    fileReference: model.FileReference.fromRemoteFilePath("Input2.pdf"),
    importFormatMode: "KeepSourceFormatting"
})
const documentEntries = [
    mergeProps
]
const documentList = new model.DocumentEntryList({
    documentEntries: documentEntries
})
const appendDocumentOnline = new model.AppendDocumentOnlineRequest({
    document: document,
    documentList: documentList
});

wordsApi.appendDocumentOnline(appendDocumentOnline)
.then((appendDocumentOnlineResult) => {    
    console.log("Result of AppendDocumentOnline: ", appendDocumentOnlineResult);
    
    const splitDocumentOnline = new model.SplitDocumentOnlineRequest({
        document: appendDocumentOnlineResult,
        format: "png",
        zipOutput: true
    });

    wordsApi.splitDocumentOnline(splitDocumentOnline)
    .then((splitDocumentOnlineResult) => {        
        console.log("Result of SplitDocumentOnline: ", splitDocumentOnlineResult);
    });
});
